Reinforced thermoplastic composite structure wall-pipe pipe workpiece and strip material and complete set of production devices thereof

Abstract

The invention discloses a reinforced thermoplastic composite structure wall-pipe strip material, which comprises a base plate, a reinforcing rib integrated with the base plate, and a reinforcing sectional material integrated with the reinforcing rib or simultaneously integrated with the base plate and the reinforcing rib, wherein the reinforcing sectional material is extruded and compounded with a thermoplastic material layer of the reinforcing rib, or simultaneously extruded and integrated with a thermoplastic material layer of the base plate and the reinforcing rib, and is completely coated by the thermoplastic material layer. The reinforced thermoplastic composite structure wall-pipe strip material can significantly improve the ring stiffness of a pipe workpiece. The invention also discloses a reinforced thermoplastic composite structure wall-pipe pipe workpiece, which is provided with smooth and flat inner walls and spirally surrounding reinforced thermoplastic composite reinforced structure outer walls with separation distances. The invention also discloses a complete set of production devices of reinforced thermoplastic composite structure wall-pipes for producing the reinforced thermoplastic composite structure wall-pipe strip material. By the production device, the continuous production of the reinforced thermoplastic composite structure wall-pipe strip material and the reinforced thermoplastic composite structure wall-pipe pipe workpiece can be synchronously realized and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of reinforced thermoplastic composite structure wall pipes, in particular to a reinforced thermoplastic composite structure wall pipe material, a strip and a complete production device thereof. Background technique [0002] The protection of water resources is an important part of protecting the ecological environment. At present, the main cause of groundwater pollution is the leakage of urban or industrial sewage pipes. For this reason, traditional cast iron pipes and reinforced concrete pipes have been gradually or are being replaced by various types of buried plastic structural wall pipes. [0003] There are two main processes for plastic structural wall pipes: direct extrusion and winding. The plastic structural wall pipes formed by winding are formed by continuous winding of plastic hollow strips or plastic special-shaped strips. This process is suitable for the manufacture of large-diameter and full-s...
